I just spent a solid week looking for a bug in my code. I was poring over and over all the sections of code that changed between the last working version and the current version. I even had a hunch what I should be looking for, but nothing was showing up. Tonight, on a whim I found the problem. It belonged to a section of code that had not changed in 6 or 8 months and which was insignificant and unused until recently. The bug took 1/2 second to correct once spotted.
Seems like I get stuck about once a year on a bug like this. :(
